Hi I removed SketchMorph and adapted ImageMorph to be invoked instead. Now sketchMorph has ColorPickerMorph as a subclass so since I did not get the time to understand how we can substitute ColorChooserMorph here is what I did: I fileout sketchmoroh from another image, renamed it with emacs with a funky name and fileout ColorPickerMorph and made sure to use this new superclass. In the process I added some example in comment to ColorChooserMorph. Now it would be good if one of you could have a look at the slice I published in the inbox. alain yes we got rid of it :) http://code.google.com/p/pharo/issues/detail?id=2109 Stef
